中文摘要：

总结并分析了建筑信息模型（BIM）应用于结构工程领域过程中所存在的问题,提出了建筑信息模型方法学（结构BIM方法学）理论,认为该理论是由结构BIM技术的基本原则与结构BIM模型理论这两大分支构成;应用数学建模方法对结构BIM技术的基本原则进行了数学建模与理论分析,解决了结构从业人员对结构BIM技术应用方式与研究方法模糊的问题,同时基本原则的数学模型也为未来结构BIM技术的定量化研究打下了基础。最后阐述了构建结构BIM方法学理论的实践意义,并引出了结构BIM模型这一理论分支。所得结论为进一步讨论结构BIM模型的组织构架方法奠定基础。

英文摘要：

The authors analyzed the problem of building information modeling（BIM）applied in structural engineering field,and put forward the theory of BIM-methodology which was composed of the basic principle of BIM and structure BIM model.The basic principle of BIM was modeled and analyzed by mathematical-modeling.The conclusion of the modeling solved the problem of using and researching BIM by the structural engineers.Meanwhile,the model of the theory also laid the groundwork for the future quantitative BIM study.In the end,the important practical significance of the theory was discussed and the branch of structure BIM model was raised.The conclusion lays the foundation for further discussion of organization structure of BIM model method.
